DETAILED DESCRIPTION

The present disclosure may be understood by reference to the following detailed description, taken in conjunction with the drawings as described below. For purposes of illustrative clarity understood, various drawings of this disclosure show a portion of the electronic device, and certain elements in various drawings may not be drawn to scale. In addition, the number and dimension of each device shown in drawings are only illustrative and are not intended to limit the scope of the present disclosure.

Certain terms are used throughout the description and following claims to refer to particular components. As one skilled in the art will understand, electronic equipment manufacturers may refer to a component by different names. This document does not intend to distinguish between components that differ in name but not in function.

In the following description and in the claims, the terms “include”, “comprise” and “have” are used in an open-ended fashion, and thus should be interpreted to mean “include, but not limited to ...”.

It will be understood that when an element or layer is referred to as being “on another component or on another layer” or “connected to another component or to another layer”, it can be directly on or directly connected to the other element or layer, or intervening elements or layers may be presented. In contrast, when an element is referred to as being “directly on” or “directly connected to” another element or layer, there are no intervening elements or layers presented.

The terms “about”, “substantially”, “equal”, or “same” generally mean within 20% of a given value or range, or mean within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range.

Although terms such as first, second, third, etc., may be used to describe diverse constituent elements, such constituent elements are not limited by the terms. The terms are used only to discriminate a constituent element from other constituent elements in the specification. The claims may not use the same terms, but instead may use the terms first, second, third, etc. with respect to the order in which an element is claimed. Accordingly, in the following description, a first constituent element may be a second constituent element in a claim.

In some embodiments of the present disclosure, terms such as “connection”, “electrically connected to”, etc. regarding bonding and electrical connection, unless specifically defined, may refer to two structures which are in direct contact with each other, or are not in direct contact with each other. In case of direct connection, the endpoints of the elements on the two circuits are directly connected or connected to each other by a conductor segment, and in the case of indirect connection, there are a switch, a diode, a capacitor, an inductor, a resistor, other suitable devices, or a combination of the above, disposed between the endpoints of the elements on the two circuits, but it is not limited thereto.

In the present disclosure, the measurement methods of thickness, length and width may be measured by an optical microscope, and the thickness or width may be measured by a cross-sectional image in an electron microscope, but the present disclosure is not limited thereto. In addition, any two values or directions used for comparison may have certain errors. Additionally, references to the terms “equal to,” “equal,” “same,” “substantially,” or “substantially” throughout this disclosure generally mean within 10% of a given value or range. Furthermore, the terms “a given range is from a first value to a second value”, “a given range is within a range from the first value to the second value” means that the given range includes the first value, the second value and the other values lie in between. If the first direction is perpendicular to the second direction, the angle between the first direction and the second direction may be between 80 degrees and 100 degrees; if the first direction is parallel to the second direction, the angle between the first direction and the second direction may be between 0 and 10 degrees.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It should be understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having meanings consistent with the relevant art and the background or context of the present disclosure, and should not be interpreted in an idealized way or overly formal manner unless they are otherwise defined in the embodiments of the present disclosure.
